Basal Nikanassin/Morrissey/Swift/Success (S-1) Paleogeography (GIS data, polygon features)
The Geological Atlas of the Western Canada Sedimentary Basin was designed primarily as a reference volume documenting the subsurface geology of the Western Canada Sedimentary Basin. This GIS dataset is one of a collection of shapefiles representing part of Chapter 17 of the Atlas, Paleographic Evolution of the Western Canada Foreland Basin, Figure 1, Basal Nikanassin/Morrissey/Swift/Success (S-1) Paleogeography. Shapefiles were produced from archived digital files created by the Alberta Geological Survey in the mid-1990s, and edited in 2005-06 to correct, attribute and consolidate the data into single files by feature type and by figure.

Caribou Habitat Model for the Western Cariboo Region (2001)
Summer, Winter Alpine, and Winter Forest-Dwelling habitat model for caribou in the Itcha, Ilgachuz, and Rainbow Mountains of West-Central BC. This habitat model was developed using telemetry from the Itcha-Ilgachuz, Rainbow, and Charlotte Alplands Herds. [Season] field should be used to split the data out into separate summer, winter alpine, and winter forest-dwelling habitat models. Model development is detailed in _Apps, C. D., T. A. Kinley, and J. A. Young. 2001. Multi-scale habitat modeling for woodland caribou in the Itcha, Ilgachuz, and Rainbow mountains of west-central British Columbia.Wildlife Section, Ministry of Water, Land and Air Protection, Williams Lake, British Columbia, Canada_. See also: https://catalogue.data.gov.bc.ca/dataset/caribou-habitat-model-for-the-western-cariboo-region-2017-. __Note: The 2017 habitat model covers a similar area, but does not supersede the 2001 habitat model.__
Forest Drought Risk Assessment Tool
Forest Drought Risk Assessment Tool (ForDRAT) provides estimates of stand-level drought risk for various BC tree species (Interior only at this point). Drought risk estimates are provided across different biogeoclimatic units and relative soil moisture regimes for both current and future climates. The data are currently provided in a spreadsheet, with the following columns: 1. BGC: Biogeoclimatic zone, subzone and variant. 2. Period: Data are provided for three historical periods: (i) 1961-1990 climate normal period; (ii) 1971-2000; and (iii) 1981-2010. Projected drought risk is provided for three future periods: (i) 2020 (2011-2040); (ii) 2050 (2041-2070); and (iii) 2080 (2071-2100). 3. SMR_text: Text description of relative soil moisture regime. 4. SMR: Integer code of relative soil moisture regime. 5. AET_PET: Mean annual ratio of actual to potential evapotranspiration. 6. The remaining columns provide estimated drought risk by species. Species codes are as follows: (i) Pl = lodgepole pine; (ii) Sx = hybrid white spruce; (iii) Fd = Douglas-fir (interior variety); (iv) Bl = subalpine fir; (v) Cw = western redcedar; (vi) Hw = western hemlock; (vii) Lw = western larch; (viii) Py = ponderosa pine; (ix) Ac = black cottonwood; and (x) At = trembling aspen. More species will be added over time. Details on ForDRAT development are provided in the following resources: DeLong et al. 2022: http://library.nrs.gov.bc.ca/digipub/Tr141.pdf DeLong et al. 2019: https://www.for.gov.bc.ca/hfd/pubs/Docs/Tr/TR125.pdf Foord et al. 2017: https://www.for.gov.bc.ca/hfd/pubs/Docs/En/En119.htm Nitschke and Innes. 2008: https://www.sciencedirect.com/science/article/abs/pii/S0304380007004061?via%3Dihub
Sponge Fields in the Gulf (Western IIA Trawl Sample)
Polygons denoting concentrations of sea pens, small and large gorgonian corals and sponges on the east coast of Canada have been identified through spatial analysis of research vessel survey by-catch data following an approach used by the Northwest Atlantic Fisheries Organization (NAFO) in the Regulatory Area (NRA) on Flemish Cap and southeast Grand Banks. Kernel density analysis was used to identify high concentrations and the area occupied by successive catch weight thresholds was used to identify aggregations. These analyses were performed for each of the five biogeographic zones of eastern Canada. The largest sea pen fields were found in the Laurentian Channel as it cuts through the Gulf of St. Lawrence, while large gorgonian coral forests were found in the Eastern Arctic and on the northern Labrador continental slope. Large ball-shaped Geodia spp. sponges were located along the continental slopes north of the Grand Banks, while on the Scotian Shelf a unique population of the large barrel-shaped sponge Vazella pourtalesi was identified. The latitude and longitude marking the positions of all tows which form these and other dense aggregations are provided along with the positions of all tows which captured black coral, a non-aggregating taxon which is long-lived and vulnerable to fishing pressures.These polygons identify sponge grounds from the broader distribution of sponges in the Southern Gulf region as sampled by Western II A gear in the Gulf biogeographic zone. A 3 kg minimum threshold for the sponge catch was identified as the weight that separated the sponge ground habitat from the broader distribution of sponges with these research vessel tow data and gear type.
